ALBERT L. KLEES, OF LONG BEACH, NEW YORK, ASSIGNORTO SURFACE COMBUSTIONCORPORATION, OF TOLEDO, HIO, A CORPORATION OF NEW YORK ens BnnnmeAPPARATUS Application filed July 10, 1929, Serial fhis invention relatesto gas burning apparatus for house heating furnaces originally designedfor burning solid fuel; and has for its object to provide a gas burningapparatus of such form and construction that a' major portion thereofmay be built as a unit for positioning in front of the ash pit chamberto form in efiect a lateral extension thereof from the side door openingtherein, the other portion being so constructed as to permit its beingpositioned within the furnace; and withal to provide a gas burningapparatus which shall be efficient in operation, simple in constructionand otherwise particularly well adapted for its intended purpose.

' The present application is a continuation in part of my application,Serial No. 202,833, filed July 1,1927.

The ordinary house heating furnace is provided with grates for burningsolid fuel. To

install my improvedgasburning apparatus it is necessary to remove'thegrates andalso the door for the ash pit chamber.

In accordance with the present invention,

there is provided a casing 10 for supplying sectional view of the377,100. Renewed November 18, 1931.

secondary air to the burner 26 which'replaces the furnace grates. Thecasing extends from the door opening in the ash pit chamber 12 wherebyto form in effect a lateral extension of said chamber. The admission ofair into the casing is controlled by a damper 34 shown as positioned inthe top wall of the casing, means being provided for opening and closingthe damper at the same time that the main gas valve for the burner isopened and closed.

In the present instance, the gas valve actuating mechanism is shown ascomprising a manually actuable lever 36 projecting from one side of ahousing 35 wherein is contained mechanism for causing the valve to,openand close with a snap action. The lever 36 and damper 34are sointerconnected, by mechanism generally indicated .at 46, that when thelever 36 is moved to actuate the gas valve 20 it will also actuate thedamper, the gas valve anddamper being concurrently opened and closed asalready stated.

For illustrative purposes, nism 46 is shown as comprising twolink-connected bell cranks 11 and 15, the latter being connected to thedamper 34 and mer to the lever 36 by a link 19. The bell crank 11 isshown as supported on a bracket- 13 extending fromthe housing 35.

The snap action mechanism comprises a the said mechathe forhead 44secured to the stem of the gas valve in 35. A link 37 connects the'center of the sp fing 38 with the manual controlling lever 36. It willbe, of course, understood that when the middle of the spring is movedpast the fulcrum points 48, the outer end ofthe links 40 will moveupwardly or downwardlyas the case may be, thereby actuating the 1 .valvestem, to ,close .or open the valve. Snap action mechanism of the typeshown is well known in the; art.- In the present instance thereis-al'so' shown associated with the head 44 a lever 48, the function ofwhich is to prevent the gas valve from being opened I upturnedextensions by hangers 53.

to provide an annular unless a thermostatic device 50, controlled by theburner pilot 47 permits.

The gas burner is of the multi-jet ringtype shown as comprising twosimilar sections 26 individually supplied with combustible mixture fromindividual mixing tubes 24 within the casing 10, the tubes deliveringinto individual pipes 52, which in turn deliver to the individual burnersections, the pipes having upturned extensions 54 to which the burnersections are detachably connected.'

The pipes may be supported adjacent tl i eir he burner sections aresupported in any suitable manner as by lateral arms 62 projecting from acommon hub removably supported on a central standard 60.

Surrounding the burner in spaced relation passage 55 is a casing 56v andspaced from the inner rim of the burner to provide an annular passage 57is a plate 58. The casing 56 is in effect a detachable extension of thecasing 10, the casing 56 being split as indicated at 56. The plate 58 isdetachably supported on the standard 60. The purpose of the passages 55and 57 is to confine and direct the secondary air, supplied by thecasing 10, to flow paths immediately adjacent the burner whereby toinsure proper combustion of the fuel.

In order that the hot gases from the burner may be deflected against thewalls of the fire pot 68,- there is provided a bafile 66 made up of anumber of wedge-shaped members 66,, the lower ends of which rest on asupport 64 supported on the standard and the upper ends of which leanagainst the fire pot wall. A cut-out 70 in the top of each baflle memberinsures free escape of the spent heating gases. In order to permit agiven number of baflle members to be adjusted to fire pots of differentdiameters, and at the same time to prevent open gaps between themembers, the latter are constructed to overlap as ,shown in Fig. 7.

At the outer end of the casing 10 is a closure 14 provided with openings22 for admitting air to the respective mixing tubes 24, the walls of theopenings being extended to form tubular bosses 23 whereinto the tubesproject. Associated with each tube is a jet orifice gas nozzle 27controlled by a needle valve 32 s which is mounted in a body 28 whichalso forms a support for a shutter 30 for controlling the admission ofair to the mixing tubes.

The nozzles 27 are mounted in the ends 26 lof conduits 16 formed in theclosure 14, the

conduits having a common inlet whereinto the gas supply pipe 18discharges. As clear- 1y shown in Fig. 5, the"wa-lls of the conduits 16are extended into the openings 22, the end of each conduit terminatingin a-tubular portion. in one end of which the nozzle 27 1s mounted andin the other end of which the body 28 is mounted.

The manufacturing and installation. advantages of the apparatus as awhole will be readily appreciated by those skilled in the art, it beingnoted that the casing 10: and the parts housed and supported therebyconstitutes a unit which forms in effect a lateral extension of the ashpit chamber.
